Abstract

The invention provides a mining battery authority equalization management system. The mining battery authority equalization management system comprises a main control unit, an acquisition module, a control module and a signal bus. The main control unit is electrically connected with a pack end acquisition module, a discharging circuit, a charging unit and an external upper computer separately, the external upper computer is electrically connected with an operation authority module, the main control module is in communication with the acquisition module and the control module separately, and the signal bus is electrically connected with the acquisition module and the control module. By arranging the operation authority module, with an independent battery acquisition unit, the basic parameters such as pack end voltage, current and temperature and single voltage of a battery pack can be monitored in real time, and a touch screen is used for configuring battery protection parameters and achieving passive equalization of the electric quantity of a battery unit management system, so that reliable operation of a battery system is ensured, convenience is brought to use by mine workers, equalization time is shortened, and efficiency is improved.

Description

technical field [0001] The invention relates to a management system, in particular to a mining battery authority balance management system. Background technique [0002] Although lithium-ion battery technology has made great progress in recent years, and the various performances of lithium batteries have been significantly improved; however, inconsistencies between single cells in lithium battery packs are still common. There are differences in various parameters of lithium batteries in the production process, and these differences are manifested as inconsistencies in the internal resistance, capacity, open circuit voltage, charge and discharge voltage platform, etc. of lithium batteries. With the increase in the number of charging and discharging of lithium batteries in actual operation, as well as the influence of various factors such as temperature and self-discharge, these differences will continue to expand, making the performance differences between lithium battery cel...
